Glycolysis is the process of breakdown of glucose or similar hexose sugar to two molecules of pyruvic acid through a series of enzyme mediated reactions (occurs in cytosol) releasing some energy (as ATP) and reducing power (as NADH 2). It is common to both plant and animal cells and to both aerobic and anaerobic modes of respiration. 2 ATP and 2 NADH are generated during the process of glycolysis using the energy that was originally in one molecule of glucose. Which of the following processes takes place in the cytosol of a eukaryotic cell? Under aerobic conditions the end product of glycolysis is pyruvic acid.

Glycolysis occurs in the cytoplasm of the cell during both anaerobic and aerobic respiration. ATPb. 264 ). Glycolysis is the metabolic pathway where one molecule of glucose (C 6 H 12 O 6) converts into pyruvic acid with the help of enzyme. (D): The end product of glycolysis is pyruvic acid whereas acetyl CoA is the connecting link between glycolysis and Krebs cycle. It is important in biochemistry as it is the product of Glycolysis, the breaking down of a glucose molecule. Pyruvic acid is a colorless liquid with a smell similar to that of acetic acid.It is miscible with water, and soluble in ethanol and diethyl ether.In the laboratory, pyruvic acid may be prepared by heating a mixture of tartaric acid and potassium hydrogen sulfate, or by the hydrolysis of acetyl cyanide, formed by reaction of acetyl chloride with potassium cyanide: glycolysis.

Electron carriers bring electrons from the first three steps to the electron transport chain, and ATP is made. Pyruvic acid is formed as an end product of glycolysis, a process that breaks down glucose (a six-carbon molecule) into two molecules of pyruvate (a three-carbon molecule) and simultaneously yields a small net gain of the universal energy storage molecule adenosine triphosphate (ATP), used to power cellular function.
